EGG-TESTING DEVICE.

Specification of Letters Patent.'

Application led November 9, 1911. Serial No. 659,323.

T0 all ytlf/wia it may concern? Be it known that I, YVILLIAM HUMPHREY, a citizen of the United States, residing at Auburn, in the county of Nemalia and State of Nebraska., have invented certain new and useful Improvements in Egg-Testing Devices; and I do declare rthe followiiigto be a full, clear, and exact description'of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in One object of the an egg testing device having arranged therein an electric lamp and which is provided with an improved construction and arrangement of switch'adapted t'obe automatically operated when the eggs are placed in position for testing.. i I

Another object-is to provide a device of this character which will be simple and inexpensive in construction, eilicient, lreliable and economical in operation and which is well adapted to the purpose for which it designed.

lVith these and other'objects in View the invention consists of certainvnovel features of construction, and the combination and arrangement of parts as will bel more fully described and claimed.

In the accompanying drawings; Figure 1 is a front view of an eggl testing machine embodying the invention; Fig. 2 is a horizontal sectional view thereof on the line 2-2 of Fig. 1; Fig-3 is a. vertical cross sec; tional view on the line 3-3 of Fig. 1; Fig. 4 is a. detail perspective view of the' movlight controlling switch of the device;

In the embodiment of the invention, I.

provide a box or casing 1, the top and front sides of which are provided with doors 2 and 3 which are preferably hinged respectively to the back and bottom of the box as shown. The doors 2 and 3 when closed are fastened together and held in closed position by a hook 4 as shown 0r other form of fastening device. The box is preferably provided with a handle 5 having its ends secured to the ends of the boX whereby the latter may .be readily-carried from place to place. Y

In thefront of the box are two egg-receiving holes in which are inserted sleeves invention is to provide 8 which with flanges (3, form insulators T, which are secured to the front of the box by screws 9, Vas shown. Arranged across or around .the central portion of the plate 'T and front 3 is a metal band 10 which forms the stationary member of an electric switch, Said member having connected therewith onev terminal of an electric circuit r current conducting wire 11 in which is arranged a lamp 12 and a battery 13. The lamp 12 is preferably secured to a supporting bracket 14 arranged on the inner side ofV the `front 8 of the box immediately below and in rear of the egg ,receiving openings. The battery 13 is here shown and preferably consists of a series of dry cells suitably connected together and held in position in the box 1 .by

a horizontally Adisposed board o'r plate 15. The movable nielnber of the switch coinprises va spring arm 1G secured at one end to a binding post 17 arranged through -the front 3 andl having connected to its inner endtlie other terminal of the electric circuit or current conducting wire 1'1. On the outer end of the spring arm of the switch are formed oppositely extending contact arms 18, said arms corresponding in length to the length of the plate or stationary member 1'0 ofthe switch and having their ends bent inwardly at obtuse angles-to forni combined switch operating and contact lugs 19 which project int-o the holes or openings in the front 3 and plate 7 whereby when an egg is inserted in one or both of said holes the pressure of the egg or eggs against one or both of said lugs will force the 'spring arm 16v inwardly and the contact arms 1Sv and lugs 19 into engagement with the sta- .tionary member of the switch, thus closing the latter'and completing the electric circuit through the lamp.

By constructing and arranging the movable switch member as herein shown and described, it will be seen thatl the circuit is closed and the lamp lighted each time eggs are placedin one or both of the openings in the front of the box 3 and plate 7 thus enabling thecondition' of the egg to be readily observed.A It will also be noted that as soon as the eggs are removed from the holes the spring arm of the switch will immediately open the latter, thus circuit so that the eggs are in position breaking the electric the-current is onlyl used while for testing: This arrangement of the switch provides for a. 11'
